Method and device for testing consistency of initial operation behavior of Ethernet equipment

Abstract

The invention discloses an Ethernet equipment first-operation behavior consistency testing method and device. The method comprises the steps that tested equipment is placed at the tail end of the Ethernet, the port communication state of the tested equipment and the operation state of the Ethernet are tested, and top node testing results are obtained; the tested equipment is placed on the middle section of the Ethernet, the operation state of the Ethernet is tested, and middle node testing results are obtained; the communication state between ports of the tested equipment in a power-failure state is tested, and passive bypass testing results are obtained; and whether the top node testing results, the middle node testing results and the passive bypass testing results are matched with the preset standard is tested, and the consistency of the first-operation behavior of the tested equipment is judged according to the testing results. The first-operation behavior feature of the tested Ethernet equipment can be tested comprehensively and effectively, and accordingly interoperability between Ethernet equipment produced by different plants is guaranteed.

Description

technical field [0001] The invention relates to the technical field of Ethernet testing, in particular to a method and device for testing the consistency of initial running behavior of Ethernet equipment. Background technique [0002] Existing rail transit trains have many on-board mechanical equipment, electrical equipment and auxiliary equipment, and a large number of distributed sensors and complex coupled intelligent nodes are usually installed in the vehicle, which makes the network control of rail transit trains more and more complicated. Safety detection and information systems have also increased the requirements for the performance of train network systems. [0003] The existing train communication network (Train Communicaion Network, referred to as TCN) network structure can no longer meet the requirements, so there is an urgent need for a new train communication network, the network needs to have higher real-time and reliability, better Maintainability and scalab...
